The Chamber of Secrets was allegedly created under the dungeons of Hogwarts Castle during Medieval times by Salazar Slytherin, who disagreed with the other Hogwarts founders on the merits of blood purity. The Chamber of Secrets was home to an ancient Basilisk, which, according to legend, was intended to be used to purge the school of Muggle-born students. The Chamber is lined with statues of snakes, and a large statue of Salazar Slytherin is at the center.
